Consider the following plane wave polarized in the x-z plane: E(r) = [(1+5j) ax +4 az] exp(+jky) V/m Evaluate (a) the sense of polarization, (b) axial ration in dB, and (c) tilt angle Y, in two ways: graphical and algebraic means. Here ax and a are the unit vectors in the x- and z-directions, respectively.
